Question

The latent heat of fusion in J/g of 5 substances a (mol. mass = 18) , b ( mol. mass =20) , c ( mol. mass =30) , d ( mol. mass =60 ) and e ( mol. mass = 70) . Calculate their enthalpy of fusion.


Please don't write rubbish .​

Answer 1

Answer:

When water freezes it gives up some of water's energy to environment. This released energy is heat transfer. Now at 1atm pressure during freezing of n mole of water

Heat transfer= nΔH

fusion

where ΔH

fusion

= enthalpy of fusion
